The show device command displays device information, including
name and type of connection to the system. See Section 2.3.2 for a
description of the show device command and the device naming
convention.
The operating system is on a remote disk accessed through the
Ethernet controller in slot 4 of the PCI. The name of this device,
ewa0, is used as an argument to the boot command.
This command loads Tru64 UNIX from ewa0, autobooting to
multiuser mode. See Section 2.5 for a description of the boot
command.
The boot command accepts the name of a boot device, a boot file
name through the -file option, and boot flags through the -flags
option. The environment variables bootdef_dev, boot_file, and
boot_osflags can also be used to specify the default boot device or
device list, the default boot file, and flag information. When an option
and the corresponding environment variable are both in a command
string, the option overrides the environment variable. The value of
the environment variable, however, is not changed. See Section 2.18
for information about environment variables.
The operating system banner displays.
